Rafal MajkaTinkoff-Saxo 1 of 5
After his team leader crashed out of the 2014 edition of the Tour de France, Majka stepped up big for Tinkoff-Saxo and won the polka dot jersey. He has shown that he's more than confident in the mountains, but his ambitions may, unfortunately, take a back seat to Peter Sagan's green jersey and Alberto Contador's yellow jersey chase.
Pierre RollandEuropcar 2 of 5
Thomas Voeckler was the last Frenchman to win the King of the Mountains title in 2012. Rolland wore the jersey in 2013 but ultimately lost to second-place GC finisher Nairo Quintana. With Quintana vying for the yellow jersey, Rolland has a solid shot.
Chris FroomeTeam Sky 3 of 5
Despite losing super-domestique Richie Porte to BMC Racing, Froome's supporting cast is stronger than ever. With seemingly no weaknesses, Froome has a strong chance of bringing home both the polka-dot and yellow jersey—just as he did in 2015.
Joaquim RodriguezKatusha 4 of 5
Standing on the podium in both the Giro d'Italia and the Vuelta a Espana, Rodriquez has proven himself time and time again in the mountains. Illness has put a damper on the early part of Rodriquez' season, but a fifth place finish at the Tour of the Basque Country means his form is looking up.
